Struct llhd::ir::Signature

pub struct Signature { /* fields omitted */ }

A description of the input and output arguments of a unit.

Implementations

impl Signature

pub fn new() -> Self

Create a new signature.

pub fn add_input(&mut self, ty: Type) -> Arg

Add an input argument.

pub fn add_output(&mut self, ty: Type) -> Arg

Add an output argument.

pub fn set_return_type(&mut self, ty: Type)

Set the return type of the signature.

pub fn return_type(&self) -> Type

Get the return type of the signature.

pub fn has_inputs(&self) -> bool

Check whether the signature has any inputs.

pub fn has_outputs(&self) -> bool

Check whether the signature has any outputs.

pub fn has_return_type(&self) -> bool

Check whether the signature has a return type.

pub fn inputs<'a>(&'a self) -> impl Iterator<Item = Arg> + 'a

Return an iterator over the inputs of the signature.

pub fn outputs<'a>(&'a self) -> impl Iterator<Item = Arg> + 'a

Return an iterator over the outputs of the signature.

pub fn args<'a>(&'a self) -> impl Iterator<Item = Arg> + 'a

Return an iterator over the arguments of the signature.

Inputs come first, then outputs.

pub fn arg_type(&self, arg: Arg) -> Type

Return the type of argument arg.

pub fn is_input(&self, arg: Arg) -> bool

Check whether arg is an input.

pub fn is_output(&self, arg: Arg) -> bool

Check whether arg is an output.

pub fn dump<'a>(&'a self, unit: &Unit<'a>) -> SignatureDumper<'a>

Dump the signature in human-readable form.
